And indeed We created towers in the skies, and beautified it for the beholders. 16 And We have guarded it from every outcast devil, 17 so that anyone who seeks to learn [the unknowable] by stealth is pursued by a flame clear to see. 18 And We spread out the earth, and placed mountains as anchors in it, and in it grew all things by a proper measure. 19 And We have provided therein means of subsistence,- for you and for those for whose sustenance ye are not responsible. 20 Naught is there, but its treasuries are with Us, and We send it not down but in a known measure. 21 And We send the fecundating winds, then cause the rain to descend from the sky, therewith providing you with water (in abundance), though ye are not the guardians of its stores. 22 And surely, it is We who give life and make to die. We are the Inheritor. 23 And We have already known the preceding [generations] among you, and We have already known the later [ones to come]. 24 and, behold, it is thy Sustainer who will gather them all together [on Judgment Day]: verily, He is Wise, All-Knowing! 25
